Rent a car in Rarotonga, or use the bus?
 

I've read both ways on getting a car. I'll be there about a week. I'm obviously not staying in Muri the entire time so I was thinking a car would make sense, but if the bus is highly reliable, and easy, it might make sense to do that.

I haven't read much about cab potential, so I'm not sure how easy it is to get one.

All thoughts welcome.
